Orthodontics is the branch and specialty of dentistry concerned with the supervision, guidance, and correction of the growing or mature dentofacial structures and the diagnosis, prevention, and treatment of any abnormalities associated with these structures.
The NDSE in orthodontics tests a candidate’s knowledge and clinical competence in orthodontics at the specialty level in Canada.
Canadian orthodontists are required to have broad knowledge and skills in seven domains. The blueprint below indicates the domains and approximate percentage of questions in each domain.
|Anatomy, Growth and Development||15|

The examination will consist of two three-hour parts. The examination format consists of a mix of stand-alone short- and long-answer questions that assess general knowledge and application, and case-based questions that assess diagnostic and clinical decision-making.
